Abstract (en)

[origin: EP2620803A1] An infrared polarizing filter is attached to an infrared synchronization signal radiator of a stereoscopic image display device which alternately displays right and left images by time-division with polarized light in one direction to radiate the polarized-light infrared synchronization signal. In order to solve the problem with the occurrence of crosstalk, stereoscopic image appreciation eyeglasses (30) are configured in such a manner that polarizing plates (33) are arranged side-by-side in the right and left visual fields, and visual field opening/closing liquid crystal cells (31) and tilt correcting liquid crystal cells (32) are arranged one on another on the front surfaces of the polarizing plates (33), that the polarized-light infrared synchronization signal is received by a synchronization signal receiver (37) mounted on an eyeglass frame, the visual field opening/closing liquid crystal cells (31) are driven in synchronization with each other, the right and left visual fields are alternately opened/closed relative to the display light of the stereoscopic image display device, and the voltage which is controlled by tilt angle data detected by a tilt angle detector mounted on the eyeglass frame according to the tilt of the eyeglasses is applied to the tilt correcting liquid crystal cells (32), and that the rotating light angle of the tilt correcting liquid crystal cells (32) is adjusted, and the shielded state at the time of closing the visual fields is always the maximum.
